Add the Hawaiian Punch, lemon juice, and vodka; stir to mix. Place in the freezer.

When the mixture is frozen it is ready to serve. It should be soft enough to scrape and scoop into a glass. If it is hard to scoop, allow it to set out at room temperature for a couple of minutes before serving.

Add to a cocktail glass until it is 1/2 to 2/3 full of the frozen slush. Fill the remainder of the glass with Sprite. Stir to mix and serve.
